Solution to using traveler under load??
I went thru all the agony of making your very same decision. After getting quotes thru Sailnet and Garhauer, decided on Harken Heavy Track curved to contour of my cabin top. Their equipment is much sleeker, and the cost was only a little more. I did make and have welded specific SS bases(Thru bolted to deck) to clear my hatch, but the installation is very pleasing, and works with Harken smmothness. I love Garhauer, but I agree with others, their traveler equipment is bulky and heavy.
